Wow - that's an impressive project. Ambitious and well executed. ...only part that had me confused was using like 25% of screen real estate for showing time and putting flowers on the other 75%. Artistic I guess.

My guess is he hasn't gotten to scaling the text sizes yet. It looks like all the text is the same font-size.

I think in the Reddit thread, he mentioned having to draw each character (lower-case and upper-case) pixel-by-pixel for the display.

We haven’t solved homelessness, poverty, cancer, or war. We don’t have self-piloted flying cars. But for about $90 in parts, one person can design, manufacture, and build their own bespoke smart watch. Humans have made truly remarkable progress in some very specific ways.

Although unfortunately not solved, we've made great strides in regards to child mortality, extreme poverty, war, violence, health, freedom, literacy... If you could choose any point in human history to be born, you'd be best off choosing today. https://www.gatesnotes.com/Development/Max-Roser-three-facts... https://ourworldindata.org/a-history-of-global-living-condit...

What great strides do you think America/the developed world have left to make?

How would the world be today if the government pulled all the brightest engineers off working on optimizing advertising tech at FAANG companies and paid them equally to solve these larger societal problems such as homelessness, reversing climate change/pollution, solving cancer, creating unlimited nuclear energy to replace fossil fuels, terraforming Mars for the humans, etc? I can only wonder... Thoughts?

Homelessness: unsolvable in a society where it is illegal to force someone to take care of themselves (by being sheltered). The west has decided that individual freedom is worth the cost of some people using it to choose to be homeless. I think this legal framework will make it impossible to solve homelessness.

This may be philosophically true, and probably even technically true in practice, but I suspect the vast majority of homeless would prefer better shelter than they currently enjoy. For whatever reason, these people have failed to attain better shelter within our societal system. Some people blame the system for letting these people down, other people blame the individual for not having what it takes to "make it", but I don't think you can call this a choice unless you call failure a choice.

Given that, there probably are things we can do to "solve" the vast majority of homelessness, so don't give up just yet. The few people that then legitimately choose to be homeless will probably be so scant as to be barely noticed by the rest of us.

I suspect you'd make more progress on those particular problems by funneling the same amount of money into paying all the lobbyists to stay home and play Fortnite.

>But for about $90 in parts Oh and I don't know, about $250K worth of professional experience and skills but yeah.. we have.

You can literally learn all the required skills for $0 (Youtube, online lectures, personal projects).. and a few years of your life.

You'd be better off redirecting a portion of the funding that supports their work to people with actual expertise in the fields you mentioned. Particularly when it comes to solving social problems, many of which we have answers for that aren't implemented because their expense is politically untenable.

I think William Gibson say something like, "The future is here it's just unevenly distributed." We have made great strides, but in the U.S. social mobility is lower now, life expectancy is down, so if you have to be born to a poor family, being born earlier might be better.

If you had the power to choose when to be born, you might also have the power to choose where to be born. In which case you might want to choose someplace other than the U.S.

I'm annoyed that he made a watch from scratch and its wrist twist to show screen timing is still faster than my smartwatch

What they don't show is how often it turns on when he doesn't want it to. That was probably a tough calibration to make for other manufacturers, especially when production smartwatches have much higher-resolution screens and processors that drain battery.

That is absolutely correct. Figuring out when the watch is in an upright position is trivial. Figuring out whether the user intended to actually get it to turn on is extremely hard, and it involves looking at the history of motion that preceded it, and making judgments based on a whole lot of user data.

The other problem is making the tradeoff between detecting this fast enough (to turn on all the systems that follow so that the screen can light up fast enough) and waiting long enough (so you can be extra sure that the user intended to look at the screen)

The garden path is easy. Making it work mostly unobtrusively is very hard.
